Ok, no flames, how about facts?

You cannot say that CPL ran with the same conditions as CP because 
they didn't and therefore you cannot compare the times.  This is true.

On the other hand, there were 30 classes that ran, you can do a 
statistical analysis on these.  Some of the Ladies classes would have 
run at the less favorable time and some would have run at the more 
favorable times.  Assuming that there is no conspiracy to give the 
Ladies classes the worse conditions, it is safe to assume that Ladies 
and Open classes are even distributed across the "conditions 
spectrum."

On average, this year, the Ladies Champion ran 4.69% slower than the 
Open Champion.  This is across all classes.  The closest was 1.14% 
slower.

The only possible conclusion is that the Ladies classes are slower 
than the Open classes.  (Note, this is NOT the same as Ladies are 
slower then Men.  Different analysis would have to be done for that 
and the sample of "people at the Nats" is not an appropriate sample 
for that analysis.  And yeah, I got a C in Statistics in college, but 
at least I took the class...)

I make no claims as to why this is.  Nor do I make public any 
opinions I may have on the issue.  (And why do I have time to do 
this?  I don't but the DSL installation person is here now and I 
can't do any real work... :-)
